01 - Toast all 6 bread slices in a toaster until golden brown and lightly crisp.
02 - Spread mayonnaise evenly over one side of each toasted bread slice.
03 - Place 2 toast slices mayo-side up on a clean work surface. Layer each with half of the turkey or chicken, a slice of ham if using, 2 bacon slices, tomato slices, and lettuce. Season with salt and pepper to taste.
04 - Top each stack with a second toasted bread slice, mayo-side up. Repeat layering with remaining turkey or chicken, ham, bacon, tomato, and lettuce. Season again lightly with salt and pepper.
05 - Place the third toasted bread slice on top of each sandwich, mayo-side down. Insert 2 toothpicks into each sandwich to hold the layers together, then cut diagonally into quarters to form classic club wedges.
06 - Serve immediately while the toast is still warm and crisp. Pair with potato chips, a side salad, pickles, or coleslaw if desired.
